Arteria profunda brachii
Arteria Profunda Brachii (also known as the Deep Artery of the Arm or Deep Brachial Artery) is a large vessel that provides blood supply to the upper arm. It is a branch of the brachial artery, which is the main blood vessel of the arm.
Anatomy[edit | edit source]
The Arteria Profunda Brachii typically arises from the brachial artery just below the lower border of the teres major muscle. It then travels posteriorly with the radial nerve through the triangular interval, a gap between the humerus and the two heads of the triceps brachii muscle.
The artery gives off several branches that supply the triceps brachii muscle, the deltoid muscle, and the shoulder joint. It ends by dividing into the middle and radial collateral arteries, which contribute to the arterial supply of the elbow joint.
Clinical Significance[edit | edit source]
Due to its location, the Arteria Profunda Brachii can be affected by trauma to the arm, potentially leading to hemorrhage or ischemia. It may also be involved in conditions such as thrombosis or aneurysm.
Knowledge of the artery's anatomy is important in surgical procedures involving the arm, such as fracture repair or arterial bypass grafting. It can also be used as a landmark in diagnostic procedures like angiography.
